Shrub rose plant named ‘BOZFRA221’

ABSTRACT

A new and distinct cultivar of  Rosa  plant named ‘BOZFRA221’ is disclosed, characterized by large, orange-pink double flowers. Plants have semi-upright habits and are tolerant to rust and downy mildew. The new variety is a  Rosa , normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Rosa hybrida.

Variety denomination: ‘BOZFRA221’.

BACKGROUND OF THE INVENTION

The new Rosa cultivar is a product of a planned breeding program conducted by the inventor, Biljana Bozanic Tanjga, in Temerin, Serbia. The objective of the breeding program was to produce new profusely flowering shrub rose plants with good disease resistance, and large, vibrantly colored blooms. The cross resulting in this new variety was made during May of 2013.

The seed parent is the unpatented Rosa ‘Clair Renaissance’. The pollen parent is the unpatented Rosa ‘Dominica’. The new variety was discovered in June of 2014 by the inventor in a group of seedlings resulting from the 2010 crossing, in a research nursery in Temerin, Serbia.

Asexual reproduction of the new cultivar was performed by softwood cuttings at a research nursery in Mali Idjos, Serbia in 2015, and has shown that the unique features of this cultivar are stable and reproduced true to type in multiple successive generations.

SUMMARY OF THE INVENTION

The cultivar Rosa ‘BOZFRA221’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘BOZFRA221’. These characteristics in combination distinguish ‘BOZFRA221’ as a new and distinct Rosa cultivar:

-   -   1. Orange-pink flowers.     -   2. Large, double flowers.     -   3. Semi-upright habit.     -   4. Tolerant to rust and downy mildew.

Plants of the new cultivar ‘BOZFRA221’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of the new cultivar ‘BOZFRA221’ differ in the following;

-   -   1. Plants of the new variety are not as tall as plants of the         seed parent.     -   2. Flowers of the new variety have more petals than flowers of         the seed parent.     -   3. Flowers of the new variety have a medium fragrance, while         flowers of the seed parent have a strong, old rose fragrance.     -   4. Flower color of the new variety is orange-pink, while the         flower color of the seed parent is light pink.

Plants of the new cultivar ‘BOZFRA221’ are similar to plants of the pollen parent in most horticultural characteristics, however, plants of the new cultivar ‘BOZFRA221’ differ in the following;

-   -   1. Plants of the new variety are about 70 cm in height, while         plants of the pollen parent are about 60 to 80 cm in height.     -   2. Flower color of the new variety is orange-pink, while the         flower color of the pollen parent is red.     -   3. Flowers of the new variety have more petals than flowers of         the pollen parent.     -   4. Flowers of the new variety have a medium fragrance, while         flowers of the pollen parent have a mild fragrance.     -   5. Plants of the new variety are re-blooming, while plants of         the pollen parent bloom throughout the season.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘BOZFRA221’ are comparable to the commercial variety Rosa ‘Auscousin’, U.S. Plant Pat. No. 25,064. The two Rosa varieties are similar in most horticultural characteristics; however, the new variety ‘BOZFRA221’ differs in the following:

-   -   1. Flowers of the new variety have a flat profile, while flowers         of this comparator are mostly flat, but outermost ring of petals         curve and cup interior petals.     -   2. The new variety has a more compact growth habit than this         comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘BOZFRA221’ grown in a 2-gallon container. Age of the plant photographed is approximately 5 months.

FIG. 2 illustrates a close-up view of flowers of ‘BOZFRA221’.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
